Traction Control System Warning Light
United States Canada (Analog Only)
This warning light should come on briefly when the
engine is started.
If the warning light doesn't come on then, have it fixed
so it will be ready to warn you if there's a problem. If it
stays on, or comes on when you're driving, there may be
a problem with your traction control system and your
vehicle may need service. When this warning light is
on, the system will not limit wheel spin. Adjust your
driving accordingly.The traction control system warning light may come on
for the following reasons:

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature
Warning Light
This light tells you that your
engine has overheated. You
should stop your vehicle
and turn the engine off as
soon as possible. A warning
chime should also sound if
this light comes on.
As a check, the light should come on for a few seconds
when you start your engine. See ªEngine Overheatingº
in the Index.

BATTERY VOLTAGE LOW - 6: This message
will appear when the electrical system is charging less
than 10 volts or if the battery has been drained. If this
message appears immediately after starting, it is
possible that the generator can still recharge the battery.
The battery should recharge while driving but may take a
few hours to do so. Consider using an auxiliary charger
(be sure to follow the manufacturer's instructions) to
boost the battery after returning home or to a final
destination. If this message appears while driving or
after starting your vehicle and stays on, have it checked
immediately to determine the cause of this problem.
To help the generator recharge the battery quickly, you
can reduce the load on the electrical system by turning off
the accessories. You can monitor battery voltage on the
DIC by pressing the INFO button. The normal range
is 11.5 to 15.5 volts.
CHANGE ENGINE OIL
- 82: This means that the
life of the engine oil has expired and it should be
changed within 200 miles. See ªEngine Oilº and
ªFilter Recommendationsº in the Maintenance Schedule
booklet. After an oil change, the Oil Life Indicator must
be reset. See ªOil Life Indicator, How to Resetº in
the Index.CHANGE TRANS FLUID
- 47: This message will
appear when it is time to replace the transaxle fluid. See
the Maintenance Schedule booklet for the proper fluid
and change intervals.
CHECK BRAKE FLUID
- 37: This message will
display if the ignition is in ON to inform the driver that
the brake fluid level is low. Have the brake system
serviced by a technician as soon as possible. See ªBrake
System Warning Lightº in the Index.
CHECK COOLANT LEVEL
- 2: This message
will appear when there is a low level of engine coolant.
Have the cooling system serviced by a technician as
soon as possible.
CHECK FUEL GAGE
- 50: (Analog Cluster Only)
This message will appear when the fuel supply is less
than 5 gallons (18.9 L) and the display is turned off.
A single chime will also sound when this message
is displayed.
CHECK GAS CAP
- 61: This message will appear if
the gas cap has not been fully tightened. You should
recheck your gas cap to ensure that it's fully tightened.

Remember that the Night Vision System can only
help you see objects that are warmer or colder than the
surroundings. It can't sense things like brake lights,
turn signals or emergency flashers, traffic lights or signs.
In dry, clear weather, the system can see pedestrians,
animals and the direction of the road ahead. In light rain,
light snow or light fog the image may not be as clear
and you may not be able to see the direction of the road
ahead. In more severe weather conditions, the image
may be unclear and not usable.
CAUTION:
Don't use the Night Vision System to replace
your normal view of the road ahead. It can't
tell you how far away things are. It senses only
warmer or colder objects, not all objects. Driving
by staring at the image might cause you not to
see important objects in the road ahead. If you
don't see something in time, you could have a
crash in which you and others could be injured.
Use the Night Vision System only as a driving aid.
It is also important to keep your windshield, the HUD
(Head
-Up Display for the night Vision System) lens and
the camera lens clean. If you do not keep everything
clean, system performance may be affected. The HUD
system is located on the driver's side of the instrument
panel, next to the windshield and the camera is located
behind the center of the front grille. Use only household
glass cleaner and a soft cloth. Wipe gently and
dry thoroughly.
NOTICE:
When cleaning, be careful not to scratch the
HUD or camera lenses. Do not spray glass
cleaner directly on the HUD lens because
the cleaner could leak inside the unit and
cause damage.
The camera must also be aligned to work correctly.
If the camera needs adjustment, see your dealer.
Do not attempt to adjust the camera yourself.

A chime will sound the first time an object is detected.
URPA can detect objects 3 inches (7.6 cm) and wider,
and at least 10 inches (25.4 cm) tall, but it cannot detect
objects that are above trunk level. In order for the rear
sensors to recognize an object, it must be within
operating range.
If the URPA system is not functioning properly, the
display will flash red, indicating that there is a problem.
The light will also flash red while driving if a trailer is
attached to your vehicle, or a bicycle or object is on the
back of, or hanging out of your trunk. The light will
continue to flash until the trailer or the object is
removed and your vehicle is driven forward at least
15 mph (25 km/h). It may also flash red if the ultrasonic
sensors are not kept clean. So be sure to keep your rear
bumper free of mud, dirt, snow, ice and slush or the
system may not work properly. If after cleaning the rear bumper and driving forward at
least 15 mph (25 km/h), the display continues to flash
red, see your dealer. It may also flash red if your vehicle
is moving in REVERSE (R) at a speed greater than
3 mph (5 km/h). Other conditions that may affect
system performance include things like the vibrations
from a jackhammer or the compression of air brakes
on a very large truck.
As always, drivers should use care when backing up a
vehicle. Always look behind you, being sure to check
for other vehicles, obstructions and blind spots. For
cleaning instructions, see ªCleaning Your Vehicleº in
the Index.

Avoid needless heavy braking. Some people drive
in spurts
-- heavy acceleration followed by heavy
braking
-- rather than keeping pace with traffic.
This is a mistake. Your brakes may not have time to
cool between hard stops. Your brakes will wear out
much faster if you do a lot of heavy braking. If you
keep pace with the traffic and allow realistic following
distances, you will eliminate a lot of unnecessary
braking. That means better braking and longer
brake life.
If your engine ever stops while you're driving, brake
normally but don't pump your brakes. If you do, the
pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and the
brake pedal will be harder to push.
Anti-Lock Brakes (ABS)
Your vehicle has anti-lock brakes (ABS). ABS is an
advanced electronic braking system that will help
prevent a braking skid.
When you start your engine and begin to drive away,
your anti
-lock brake system will check itself. You may
hear a momentary motor or clicking noise while this test
is going on, and you may even notice that your brake
pedal moves a little. This is normal.
If there's a problem with
the anti
-lock brake system,
this warning light will stay
on. See ªAnti
-Lock Brake
System Warning Lightº in
the Index.

4-9
Remember: Anti-lock doesn't change the time you need
to get your foot up to the brake pedal or always decrease
stopping distance. If you get too close to the vehicle in
front of you, you won't have time to apply your brakes
if that vehicle suddenly slows or stops. Always leave
enough room up ahead to stop, even though you have
anti
-lock brakes.
Using Anti
-Lock
Don't pump the brakes. Just hold the brake pedal down
firmly and let anti
-lock work for you. You may hear the
anti
-lock pump or motor operate, and feel the brake
pedal pulsate, but this is normal.
Braking in Emergencies
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even the very best braking.
Traction Control System
Your vehicle has a traction control system that limits
wheel spin. This is especially useful in slippery road
conditions. The system operates only if it senses that
one or both of the front wheels are spinning or
beginning to lose traction. When this happens, the
system works the front brakes and reduces engine
power to limit wheel spin.The TRACTION ENGAGED message will display on
the Driver Information Center when the traction control
system is limiting wheel spin. See ªDriver Information
Center Messagesº in the Index. You may feel or hear
the system working, but this is normal.
If your vehicle is in cruise control when the traction
control system begins to limit wheel spin, the cruise
control will automatically disengage. When road
conditions allow you to safely use it again, you may
reengage the cruise control. See ªCruise Controlº
in the Index.United States Canada
This warning light will come on to let you know if
there's a problem with your traction control system.
See ªTraction Control System Warning Lightº in the
Index. When this warning light is on, the system will
not limit wheel spin. Adjust your driving accordingly.

4-19
Driving too fast through large water puddles or even
going through some car washes can cause problems, too.
The water may affect your brakes. Try to avoid puddles.
But if you can't, try to slow down before you hit them.
CAUTION:
Wet brakes can cause accidents. They won't work
as well in a quick stop and may cause pulling to
one side. You could lose control of the vehicle.
After driving through a large puddle of water or
a car wash, apply your brake pedal lightly until
your brakes work normally.
Hydroplaning
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride on the water.
This can happen if the road is wet enough and you're
going fast enough. When your vehicle is hydroplaning,
it has little or no contact with the road.
Hydroplaning doesn't happen often. But it can if your
tires do not have much tread or if the pressure in one or
more is low. It can happen if a lot of water is standing on
the road. If you can see reflections from trees, telephone
poles or other vehicles, and raindrops ªdimpleº the
water's surface, there could be hydroplaning.

2. Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren't touching
each other. If they are, it could cause a ground
connection you don't want. You wouldn't be able
to start your vehicle and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump start procedure. Put an automatic transaxle
in PARK (P) or a manual transaxle in NEUTRAL
before setting the parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter or accessory power outlets. Turn off all lamps
that aren't needed as well as radios. This will avoid
sparks and help save both batteries. In addition,
it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn't be covered by
your warranty.
Open the hoods and locate the battery on the other
vehicle and the remote positive (+) terminal located
on the passenger's side of the engine compartment
of your vehicle. (You will not see the battery under
the hood of your vehicle, since it is located under
the rear seat on the passenger's side.) Find the
positive (+) and negative (
-) terminals on the
battery in the other vehicle.
You do not need to access your battery for jump
starting. The remote positive (+) terminal, located
on the passenger's side of the engine compartment,
is for this purpose.

Brakes
Brake Fluid
Your brake master cylinder reservoir is on the driver's
side of the engine compartment. See ªEngine
Compartment Overviewº in the Index. It is filled with
DOT
-3 brake fluid.
There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the brake
fluid goes down to an acceptable level during normal
brake lining wear. When new linings are put in, the fluidlevel goes back up. The other reason is that fluid is
leaking out of the brake system. If it is, you should have
your brake system fixed, since a leak means that sooner
or later your brakes won't work well, or won't work
at all.
So, it isn't a good idea to ªtop offº your brake fluid.
Adding brake fluid won't correct a leak. If you add fluid
when your linings are worn, then you'll have too much
fluid when you get new brake linings. You should add
(or remove) brake fluid, as necessary, only when work is
done on the brake hydraulic system.
CAUTION:
If you have too much brake fluid, it can spill on
the engine. The fluid will burn if the engine is
hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work is done on the brake
hydraulic system.
When your brake fluid falls to a low level, your brake
warning light will come on. See ªBrake System Warning
Lightº in the Index.

6-32 Brake Wear
Your vehicle has four-wheel disc brakes.
Disc brake pads have built
-in wear indicators that make
a high
-pitched warning sound when the brake pads
are worn and new pads are needed. The sound may
come and go or be heard all the time your vehicle is
moving (except when you are pushing on the brake
pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly tighten wheel nuts in the
proper sequence to GM torque specifications.
Brake linings should always be replaced as complete
axle sets.
See ªBrake System Inspectionº in the Maintenance
Schedule booklet under Part C ªPeriodic
Maintenance Inspections.º
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.
